Packing the one-two punch of passive and active noise reduction (ANR), the Koss Quiet Zone QZ PRO headphones are the noise cancelling headphones of choice for music lovers. Their comfort and collapsibility - not to mention sound quality - make them a favorite among travelers.
For passive noise reduction, the QZPRO feature soft leatherette, closed cushions, which create a tight seal around the ear and reduce ambient noise, all while retaining bass frequencies. Active noise cancellation circuitry - embedded into each QZPRO ear cup - uses tiny microphones that sample surrounding noise and transmit that information to a processing circuit, which then generates "anti-waves" to counteract the unwanted noise and create a peaceful listening environment. No need for noise cancellation? No problem. Turn it off with the flick of a switch.
Not only do the Koss QZPRO excel at noise cancellation and reduction, they deliver uncannily high quality sound. The dynamic element bears a full frequency response of 40-20,000 Hz, allowing these noise cancelling headphones to boast deep bass and balanced midrange. Because for Koss, performance is more than a priority. It's our legacy.
